The brakes of Earlier designs, the design of its brake rim have just used on carriage for 1902, until or so nineteen twenty
Start in auto industry extensive use.The main flow of present drum brake is internal expanding type, and its brake block (brake shoe) is positioned at system
On the inside of driving wheel, brake block is flared out when brake, the inner side of friction catch wheel, reaches the purpose of brake.
For disk brake, the brake efficiency and thermal diffusivity of drum brake will be poor many, drum brake
The brake force stability of device is poor, and brake force changes very greatly on different road surfaces, is not easy to control.And because heat dispersion is poor,
Substantial amounts of heat can be assembled in braking procedure.Brake block and wheel hub are easier to that extremely complex deformation occurs under the influence of high temperature, hold
Fading of brake and the phenomenon that flutters are also easy to produce, causes retardation efficiency to decline.In addition, drum brake is in use for some time,
The space of regular adjustment brake shoe, or even whole brake rim is split out the brake powder including cleaning accumulation.Certainly, drum brake
Device is also not good for nothing, its low cost, and meets traditional design.

Face.This surface is referred to as drum.Drum brakes applies on automobile closely centurial history, but due to it can
By property and powerful brake force so that drum brakes still configures in many vehicles (be used in trailing wheel more) now.Drum-type is stopped
Car is will to be installed on brake block in brake rim toward extrapolation by hydraulic pressure, make brake block with the brake rim of vehicle wheel rotation within
Face rubs, and produces the effect of brake.
The brake rim inner face of drum brakes is exactly the position that brake gear produces brake torque.Obtaining identical brake torque
In the case of, the diameter of the brake rim of drum type braking device can upper many also smaller than the brake disc of disk type brake.Therefore carry
The oversize vehicle of reuse is merely able to the device drum brakes among the confined space of wheel rim to obtain powerful brake force.
Drum brake is exactly that two semicircular brake shoes and a brake rim are equipped inside wheel hub in fact, when
When driver steps on brake pedal, the pressure that the wheel cylinder in drum is come by oil pipe conveying acts on, and promotes brake shoes to press to brake rim
Produce braking effect.Drum brake has had very long history in motor-dom application in fact, and its biggest advantage is exactly
It is simple in construction, cost economic, but powerful brake force can be provided, under equal brake condition, the dynamics of drum brake is a bit
It is not weaker than disc brake, and is more easily installed and repairs using the brake and drive system for vehicle with tow of drum brakes.
